Johnny’s first public appearance comes juts days after he spoke to Nova’sFitzy and Wippaabout the terrifying moment he was rushed to emergency after doctors discovered the cancerous tumour.

'It's 8am in the morning and she [Tahnee] gets a call from the emergency department, saying "you need get down here immediately because he's got a brain tumour", so she was in absolute tears at the time,' Johnny said.

'And she had to drive down there and they said "look, we need to do an emergency operation." Because by this stage, I had slipped into a coma,' he added.
